I am currently deploying a notable number of 7920 wireless handsets for local VOIP communication. However I am experiencing a very high attrition rate due to the nature of my site. Handsets fail constantly costing time and money to replace or repair.
Can anybody recomend a rugedized wireless handset that will work on Call Manager 4.1 over Cisco infrastructure? like my old 7920 do.
Even a rubberized case would be of interest, preferably one that designed to protect the keypad from spills and the phone from impacts.
